There are 3M splice kits for large wire(hooking up motors)(might also come
in smaller sizes too just have not seen them yet) that use this stuff.  No
more layers of tape for LV applications.  Just bolt the wires together and
stick into the formed plastic tube and click the retaining clip and your
done.  M2'd uses this stuff in the VHF/UHF antennas in the matching block.

Neat stuff.
